OK, so for anyone wondering about DLSS:
- if you have a game rendering at 1080p at 60fps, that's 16.67ms per frame.
- if you want for game to render at 4K with DLSS Performance mode, which renders at 1080p and then upscales to 4K, that costs around 2.18ms per frame (at least that's the data I've seen, for DLSS 3, CNN model)
- so, for one frame to be rendered it needs total of 16.67+2.18=18.85ms, which translates to 53fps.
- going other way around, game needs to render at 69fps at 1080p for it to be able to take DLSS Performance upscale hit to 4K and end at 60fps.
